hi Richard, I've Updated patch and added testcases basically they are the same testcase just using different constants I tried combining them into one testcase couldn'tget the scan-assembler stuff working when multiple functions were in the assembler output I couldn't couldn't work out how to restrict the scans to only part of the assembler file. Maybe its not possible without some new dejagnu/expect fragments.
